BRITISH COLUMBIA, CANADA TREATMENT or consult No Drawing.

My ini ention relates to improvements in the treatment of coiiee the objects of which are to render it particularly beneficial as a beverage and more nutritious than coffee in its accepted form. Further objects are to combineit with cocoa or chocolate and to so treat it that the cafieine is neutralized and combined with the theobromine of the cocoa, which is inefi'ect a blending of these com- 10 ponents, imparting an aroma and flavour to the beverage which is highly desirable. I

The present process contemplates the subjection of the coffee and the cocoa to ultra violet rays preferably derived from the tungsten arc lamp, though similar rays from the quartz mercury vapour or other are lamps I and devices produce similar results.

The invention consists essentially of subjecting the coffee to ultra violet rays to neu- 9 tralize its caffeine and convertit to a nutri tious state and coating the treated'coflee with chocolate and subjecting the resultant mixture to a further treatment of said rays.

I take the greencofiee berries and pass lamp, subjecting them to its rays for a period of approzdmately 15 seconds or such other period as to enable the rays to enetrate to the innermost tissues of the berry and by so doing neutralize the caifeine and causing an intermingling of the cafieine with the proteins, oils and other protective substances such as the magnesium and calcium salts.

The cofiee is then roastedby any suitable grocess, durin which the starch content is eztritrinized an the sugar content is caramelize Before the completion of the roasting process and while the berries are ex anding, the cofiee is coated with freshly and ely ground cocoa nibs, particles of which enter the opened ores of the coffee and become fastened therem as the coffee contracts on cooling, effectively sealing the pores against the escape of volatile oils in the coffee and preventing the escape of its occluded gases such as car- If the final roastingis done by the heat from an electric are t ozone evolved from the arc permeatesthe cell structure and ap- Application filed m 28,

pears to increase the oxygen content of the finished coffee and cocoa.

Immediatel following the completion of the roasting the material iswithdrawn from the roaster and it is subjected to the rays of a mercury vapour lamp for from ten to twenty seconds, which causes a substantially complete blending of the neutralized caffeine and the theobromine of the cocoa creating a vital energy and developing and multiplying vitamines D and E.

The vitamin energies of the blended caffeine and theobromine are absolutely set free in the finished cup of coffee, hence the physiological behaviour of the true food or nutri tional coffee can be readily tested out and actually measured and the findings on recheck will be very clear and as follows: Multiplying the vitamins D and E in the cofiee and cocoa constituents i. e. caffeine, theobromine,

phosphate and carbonate of potash, proteins,

etc.

This processed coffee is remarkable for its vital energy and is possessed of great power for stimulatin to greater efiiciency the proteiolytic and diastetic ferments setting in motion that lon chain of cleavage processes in the various oodstufis, assisting in their absorbtion, assimilation and ultimate transmutation into living protoplasm.

'All normal individuals using this coffee regularly will quite uniformly in general health, spirits, natural sleep and general efiiciency and it positively does not draw on the physitime.

- What]: claim as my invention is:

- 1. The process of treating cofiee which con sists-of subjecting the green berries to ultra violet rays until the. caffeine is neutralized, of roasting the cofiee and of coat the roasted cofiee while in a heated con ition V with cocoa.

a 2. The recess of. treating cofiee which consists 0F subjecting the green berries to ultra violet rays until the cafieine is neutralized, of artially roasting the cofiee and coating it w th'cocoa and of completing, the

roasting process by direct heat from an electric arc.

3. The process oftreating cofl'ee which consists of subjecting the green berries to ultra violet rays until the cafi'eine is neutralized, of roasting the coffee and coating it with cocoa and of subjectin the whole to the rays from a mercury vapor amp whereb the neutralized caffeine and theobromine o the cocoa are blended.
